I'm a big fan of campaign wikis to keep track of things and keep everyone engaged between sessions, but since I prefer to keep them closed, there is a lot of stuff in them that is sadly never seen by anyone else. Granted, a lot of it is internal campaign info not really relevant to anyone outside the campaign, but since our current wiki, covering two campaigns so far, is starting to reach a respectable size I figure I'd start curating some of the more useful or just plain well written stuff to share with you.
(optimistically saving this space for indexing what I hope to be a lot of posts)
